IMPROVEMENT IN MODE OF ATTACHING HUBS TO AXLES.

Specification forming part of Letters Patent No. 33,577, dated October29,1861.

To all whom it may concern:

Be it known that I, C. H. DENISON, of Brattleborough, in the county of\Vindham and State of Vermont, have invented a new and Improved Mode ofAttaching Hubs to Axles, designed specially for childrens carriages; andI do hereby declare that the following is afull, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in which Figure l is a longitudinalsect-ion of a hub and axle, the former being secured on the.

latter according to my invention. a; 00, Fig. 2, indicates the plane ofsection; Fig. 2, a section of the hub taken in the line y y, Fig. 1;Fig. 3, an' external View of the back part of the hub and a portion ofthe axle.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to obtain a very simple, cheap, anddurable means for securing hubs on the axles of childrens vehicles; andit consists in having a rod fitted longitu'diiiallyin the arm of theaxle and provided at its outer end with a button attached eccentricallyto: it, the inner end of the rod being provided with an arm or crank forturning the rod and thereby adjusting the eccentric, which in a certainposition retains the hub on the axle, as hereinafter fully shown anddescribed.

To enable those skilled in the art to fully understand and construct myinvention, I

' will proceed to describe it.

A represents thehub, and B the arm of the axle C, on which arm the hubis placed and allowed to turn freely. These parts may be constructed inthe usual way.

D is the hub-band, placed, as usual, on the front end of the arm. In thefront end of the hub there is a circular recess o (shown in Figs. 1 and2,) the inner surface of the recess and the end of the arm being flushwith each other.

In the upper part of the arm B there is made longitudinally a groove E,in which a rod F is placed or fitted and allowed toturn freely. On theouter end of this rod F there is placed eccentrically a button G, whichwhen turned down will be free from the end of the hub, and consequentlywithin the area of the end of the arm B, as shown in red in Fig. 2 andin black in Fig. 1, and when turned no will lap or project over the endof the hub within the recess a, as shown in black in Fig. 2. On theinner end of the rod F there is an arm or crank b, by which the rod isturned, and consequently the button. When the arm or crank 12 is turnedin the position shown in red, Fig. 3, the button G has a downwardposition, as shown in red outline in Fig. 2, and the hub may bewithdrawn from the arm of the axle, and when said arm is turned as shownin black the button G has an upward position and overlaps the end of thehub, and consequently retains the hub on the arm. Thus by this simplearrangement, which may be applied at a small cost and without theliability of getting out of repair, the hub may be secured on the axleand readily detached therefrom when required.

The rod F may be prevented from casually turning by means of a pin a,passing through a-staple b on the axle.

' Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The rod F, fitted in the arm B of the axle C, and provided at one endwith the eccentric or button G and at the opposite end with an arm orcrank b, as and for the purpose. herein set forth.
